Conduit Bending Instructions (EMT Bender)

Accurate Stubs

Subract take-up from desired stub height.
This gives distance at which to place B on bender from
the end of the tube. To make 11", 90° bend with
1/2" tube, allow for 5" for take-up as shown
on diagram.
With 3/4" tube, allow 6"
With 1" tube, allow 8"

True Offsets

Line up arrow on either side of hook with
guideline and make 45° bend in tube. Reverse tube in
bender and adjust so that X is lined up with inch-mark
on bender corresponding to depth of offset desired. Line
up guide-line with opposite arrow and make second 45° bend.
A true offset, in the sname plane, will result between
X and Y.

Back-to-Back Bends

Make stub bend at X with guide-line centered
on either arrow located on side of hook. Measure distances
from X to Y on tube.

Reverse bender and put A on bender at Y on
tube. Line up guide-line with opposite arrow than used
when making first stub and make second bend.

Saddle Bends

C -- Center of finished Saddle Bend
X -- Double of the diameter of round object from C
Y -- Double of the diameter of round object from C

Saddle Bend, Step 1

Place tube in bender so that "C" on tube is
at notch on bender and make a 45 bend. (A 45 bend is reached
when bender handle is at a right angle to the tube.)

Saddle Bend, Step 2

Reverse tube in bender and place B on bender
at X on tube. Make return bend of 22 1/2 . Duplicate procedure
placing B on bender at Y on tube and complete saddle by
making another 22 1/2 bend.

Finished bend neatly saddles round object

Proper alignment of the guide-line with arrows
on bender hook will result in the saddle being in a straight
line.

To Straighten

Place handle of bender over stub or piece
of pipe that will fit inside and push down to the floor
in one full sweep.
